14-Stage Ripple Carry Binary Counters
General Description
The CD4020BC, CD4060BC are 14-stage ripple carry
binary counters, and the CD4040BC is a 12-stage ripple
carry binary counter. The counters are advanced one count
on the negative transition of each clock pulse. The
counters are reset to the zero state by a logical “1” at the
reset input independent of clock.
Features
s Wide supply voltage range: 1.0V to 15V
s High noise immunity: 0.45 VDD (typ.)
s Low power TTL compatibility: Fan out of 2 driving 74L
or 1 driving 74LS
s Medium speed operation: 8 MHz typ. at VDD = 10V
s Schmitt trigger clock input
Ordering Code:
